Another Series of Wet Storms Headed to Mammoth

Staff Writer

The National Weather Service has just posted a Special Weather Statement, warning about an incoming winter storm:

TWO STORMS WILL AFFECT THE REGION THE END OF THE WEEK AND THROUGH
THE WEEKEND - THE FIRST THURSDAY NIGHT INTO FRIDAY, AND THE
SECOND SATURDAY NIGHT INTO SUNDAY.

HERE IS A SUMMARY OF WHAT TO EXPECT:

STORM ONE - THURSDAY NIGHT INTO FRIDAY:
• HEAVY RAINFALL WILL LIKELY CAUSE TRAVEL DELAYS, ESPECIALLY FOR
THOSE CROSSING THE SIERRA. THE PEAK PERIOD FOR HEAVIEST
RAINFALL LOOKS TO BE EARLY FRIDAY MORNING. RAIN WILL SPILLOVER
INTO WESTERN NEVADA AS WELL, SO BE PREPARED FOR A SLOWER COMMUTE
FRIDAY MORNING WITH PONDING WATER ON ROADWAYS POSSIBLE.

• A MAJOR CONCERN WILL BE HEAVY RAIN CAUSING DEBRIS FLOWS OR ROCK
SLIDE ON RECENT BURN SCARS. ANYONE WITH INTERESTS NEAR THE
EMERALD FIRE, LITTLE VALLEY FIRE, OR MARINA FIRE BURN SCARS
SHOULD BE PREPARED. RISES ON RIVERS ARE ALSO LIKELY, BUT
FLOODING IS NOT EXPECTED ON MAINSTEM RIVERS.

• SNOW LEVELS WILL BE GENERALLY 9,500-10,000 FEET, WITH ONLY THE
HIGHEST PASSES SUCH AS TIOGA AND SONORA IMPACTED. HEAVY WET SNOW
WILL RAPIDLY ACCUMULATE ON SIERRA PEAKS ABOVE 10,000 FEET.

STORM TWO - SATURDAY NIGHT INTO SUNDAY:
• HEAVY RAIN WITH HIGHER ELEVATION SNOW. SNOW LEVELS ARE EXPECTED
TO START 7,000-8,500 FEET SUNDAY MORNING, FALLING TO 6,500-7,500
FEET BY LATE SUNDAY AFTERNOON. SNOW LEVELS MAY LOWER AN
ADDITIONAL 500 FEET BY SUNDAY NIGHT. PERIODS OF SNOW ARE POSSIBLE
ON ALL SIERRA PASSES SUNDAY AND IT IS BEST TO PREPARE FOR TRAVEL
DELAYS AND CHAIN CONTROLS.

• RAIN WILL ONCE AGAIN SPILLOVER INTO WESTERN NEVADA, BUT WILL NOT
BE AS HEAVY AS WITH THE FIRST STORM.

• WINDS: SIERRA RIDGES GUSTING 80 TO 90 MPH WITH VALLEYS GUSTING
30 TO 35 MPH.

• IF YOU NEED TO TRAVEL, THE BEST WINDOW WILL BE FROM ROUGHLY
FRIDAY NIGHT THROUGH SATURDAY AFTERNOON WITH JUST LINGERING RAIN
SHOWERS.
